Where to sell Libreboot devices

I am trying to sell a second-hand iMac 5,2 running Libreboot. I tried doing this on eBay (with non-free javascript, unfortunately) but I can't place an ad there because the shipping section does not include a shipping company that ships from where I live. Now I am looking for another place I could possibly sell this machine, I know there is interest in hardware running Libreboot, but I don't know a website where people who are on the lookout for such hardware look for it.

Does anyone here know a good place to sell such a computer?

PS Since I'm already writing this, I might as well say: If anyone is interested do not hesitate to e-mail me.

Before I put something on Libreboot's mailing list/subreddit that is possibly off-topic, I decided I should try eBay again, first. Placing the ad went ok, but when I search 'Libreboot' my listing does not show up. Does anyone have any idea why it doesn't show up? I am kind of desperate to sell this thing.
